At present, the smoking sections of aerosol generating products on the market mainly include granular, shredded or flake-like and paste-like smoking materials. Aerosol-generating products are new types of tobacco products, and their appearance, structure, molding process, and smoking mechanism are all different from traditional cigarettes. Due to the particularity of the products, there is currently no clear standard requirement, resulting in uneven quality of aerosol-generating products on the market. In particular, there is a lack of corresponding inspection methods for the filling amount of granular and paste-like smoking material aerosol generating products. The amount of the aerosol generating source material will seriously affect the smoking effect of the aerosol generating product and affect the sensory smoking quality. In the prior art, the filling amount of the aerosol generating product is mainly evaluated by weighing. However, due to the complex structure of the aerosol generating product, many materials are used, the weight fluctuates greatly, and the manual weighing method is labor-intensive and low-efficiency. .

The light inspection box is fixedly connected with the vertical light inspection box, and a fixed bracket is arranged under the horizontal light inspection box. The LED parallel backlight source and the horizontal light inspection box are all provided with LED parallel backlight sources, and at least two barrel brackets are provided on the LED parallel backlight sources of the vertical and horizontal light inspection boxes.

Therefore, it is necessary to design a lamp inspection device suitable for the filling amount of the smoking section of the aerosol generating product according to the shape of the aerosol generating product and the particularity of the filled smoking material.

In order to solve the above problems, the present invention has been proposed.

Wherein, the light inspection box 2 further includes an outer cover, which is located outside the sample accommodating groove 23 , in order to prevent the aerosol contained in the sample accommodating groove 23 from falling off the products. The outer cover is made of light-transmitting material, selected from transparent glass or transparent plastic, so as to ensure that the aerosol-generating products inside the light inspection box 2 can be observed after the outer cover is closed.

Preferably, the casing 21 is made of a light-transmitting material selected from transparent glass or transparent plastic, so as to ensure that the light beam can pass through it and penetrate to the aerosol generating product.

Preferably, the baffle 22 is an opaque material, selected from brown glass or dark plastic or metal or ceramics, that is to say, the place where the light inspection box 2 does not accommodate the aerosol generating product is opaque, In order to prevent the horizontal light beam emitted by the surface light source 1 from stimulating the eyes of the detector.
